what the mess??

So the other night Alex and I went running and as from reading the previous post, we had cramps. So last night i went on a walk with val and the same thing. I think I may have found out why... I changed my multi 4 days ago. I think im going to go back to the old kind that I had. O yes... and get a banana so our 9 mile run tonight wont be a doozie.
